SPECIFICATION forming part of Letters Patent No. 695,472, dated March 18, 1902. Application filed July 22, 1901. Serial No. 69,276. (No model.)
To ctZZ whom, it may concern:
Belt known that I, J AMES B. MILLER, a citizen of the United States, residing at Kent, in the county of Portage and State of Ohio, have invented a new and useful Improvement in Escutcheon-Plates, of which the following is specification.
My invention relates'to an improvement in escutcheon-plates for door and drawer locks; and the object of my invention is .to provide an escutcheon-plate that adds to the security of the lock with which it is used. I attain this object by the form and construction illustrated in the accompanying drawings, in which- F'gure 1 is a frontelevation of my improved escutcheon-plate, a portion of a door, and a portion of a face-casing of the doorframe; Fig. 2, a partial sectional plan on the broken line a w of Fig. 1, and Fig. 3 an edgewise elevation, of my improved escutcheon-plate. Like reference characters indicate like parts throughout the several views.
Referring to the drawings, the main body of an escutcheon-plate embodying my improvement is indicated by the reference-letter a, and it is so formed and proportioned that when applied to a door b in its proper position in relation to its lock 0 a portion of it projects beyond the edge of the door in position to overlap the face-casing cl of the door-frame when the door is closed, as shown in Figs. 1 and 3. The portion of the plate thus overlapping the casing may extend'the entire length of the plate, as shown, or may be a projection from the main body of the plate, and is provided with a tooth or detent e, projecting from its back surface for en gaging with the face-casing dby enteringa cavity f, formed therein for receiving'it when the door is closed.
the bolt more difficult.
The plate may be well secured to the door by escutcheon-pins extending. through the door and clenched; but 'a preferable way is to secure it in the manner shown in the drawings by screws g, extending through the door from the back side and threaded into bosses h, formed on the back side of the plate for receiving them,
While the escutcheomplateshown is for a key-lock," it. is to be understood that my invention is not limited thereto, but maybe embodied in the escutcheon or knob plates of permutation-locks as well.
Thisimprovedescutcheon-plate adds to the security of the lock with which it isused by interlocking with the face-casing of the doorframe, thus making it much more difficult to pry the door and the door-jamb apartiby means of a thin lever thrust into the clearance-space between them and with springlocks by covering the joint between the door and .-the face-casing, thus makingaccess to What I claim as'myinvention, and desire to secure by-Letters Patent, is
1. An 'escutcheon-plate formed and proportioned to project beyond the edge of a door when properly applied thereto; the part for. projecting beyond the door formed to inter lock with the door-frame, substantially as set forth. 7 e
2. An iescutcheon-plate formed and proportioned to project beyond the edge of a door when properly applied thereto, and having bosses for receiving retaining-screws; the part for projecting beyond the door formed to interlock with the door-frame, substantially as shown and described. I
